Biography
editDunkelman received all his degrees at the Technion - Israel Institute of Technology. He received his Ph.D. degree at the age of 25, under the supervision of Eli Biham.[3] Before joining the University of Haifa, Dunkelman held post-doctoral positions at KU Leuven, at École normale supérieure, and at the Weizmann Institute of Science.[1]
Contributions to cryptanalysis
editAmong his contributions to cryptanalysis are:
- Dissection attack – joint work with Itai Dinur, Nathan Keller, and Adi Shamir, recipient of the Best Paper Award at the Crypto 2012 conference.[4]
- Rectangle attack – joint work with Eli Biham and Nathan Keller.[5]
- New variants of differential-linear, boomerang, and slide attacks – joint works with Eli Biham, Adi Shamir, and other co-authors.[6]
- Breaking (together with Eli Biham, Sebastiaan Indesteege, Nathan Keller, and Bart Preneel) KeeLoq – a block cipher used in remote keyless entry systems by multiple companies.[7][8]
- Devising (jointly with Eli Biham) a practical attack on A5/1 – the cipher used in GSM security mechanisms.[9]
- Attacking reduced-round variants of many block ciphers, including AES, Serpent, IDEA, GOST, DES, KASUMI, MISTY1, Camellia, Skipjack and others (in joint works with various coauthors).[6]
New cryptographic primitives
editDunkelman has taken part in the design of several new cryptographic primitives:
- HAIFA construction (with Eli Biham) – a cryptographic structure used in the design of hash functions.
- KATAN and KTANTAN (with Cristophe De Canniere and Miroslav Knežević) - a family of small and efficient hardware-oriented block ciphers.[10]
- SHAvite-3 (with Eli Biham), a hash function which was one of the 14 semifinalists in the NIST hash function competition.[11]
Awards and honors
editDunkelman received the Krill Prize from the Wolf Foundation in 2014, and papers he co-authored won the Best Paper Award at the Crypto conference (2012) and at the Fast Software Encryption (FSE) conference (2012).[12][4]
